Unable to register a user in django deployement on heroku?

问题

I've deployed a django-blog web-app on heroku. Its working but with an error. When i register a new user it says user created but when I try to login through registered user it says username and password didn't match. And when I login in my admin panel then the user i registered wasn't created at all.

Here's my settings.py file

The problem seems to be with the database on heroku. I'm using PostgreSQL When I run heroku addons it shows me that I've hobby-dev database-

Add-on                                      Plan       Price  State
──────────────────────────────────────────  ─────────  ─────  ───────
heroku-postgresql (postgresql-rigid-77895)  hobby-dev  free   created
 └─ as DATABASE

The table above shows add-ons and the attachments to the current app (myblogapplication) or other apps.

I just downloaded postgresql on my machine and didn't set it up accordingly maybe and that's why its creating this error. Your help will be appreciated.

回答1:

Try to create user as superuser, if you are registered user through your form you can't able to login through admin panel. Django has a security features to prevent login from admin panel if not superuser.

python manage.py createsuperuser

Verify your local database, if it inserted properly but it is not mandatory in django because django will raise error in console but as a developer you can verify it. You can also verify is_superuser = 0 in database.
